Cache Question Regarding Security

Hi there,

A few months ago I installed W3 Total Cache, only to get hit with a pharma hack.

After reading endless raves and reviews about it, I decided to give it another shot.

I wanted to reach out to ask if there were ideal settings for this plug-in to avoid any compatibility issues with WPMU's plug-ins. I'm kind of a novice when it comes to caching and am having a very hard time optimizing my W3TC to actually speed up my site.

Caching can improve your site speed, but only when configured properly. Additionally, caching at the hardware/server level often matters more than caching at a software level (e.g., caching plugins). Consequently, what will matter most is, of course, your hosting environment. Personally, I avoid using caching plugins (and rely on server-level caching) because of the conflicts they tend to create with certain plugins/setups. However, if you want to use a caching plugin, you'll want to configure it to cache everything on your site which does not change frequently. Anything which changes on a regular, frequent basis should either be uncached by the plugin or have logic which calls the plugin to recache the content when it is updated.

I've tried both W3 Total Cache and WP Super Cache, and WP Super Cache is by far the better choice to me. It's far easier to set up, and Hostgator [even if it's not your hosting company] has a great post on configuring WP Super Cache properly.

I have over 50 WordPress sites, all running at least three WPMU plugins, and WP Super Cache plays nicely with all those plugins.
